We are moving from a network using Novell 4.11 to one using Novell 5.1 because of space. In the process Zenworks was replaced with Fortress and Cleanslate for security. We have replaced previous problems with new problems. The individual user stations seem secure, but the labs...especially the high end user labs are experiencing problems saving, losing saved files and freezing up. We would think it might be related to older machines, some 200's running on Windows 95, but an experiment running Samba with a Linux server seems to work fine. And we still have the problems on our newer machines as well. Any advice on where to focus our efforts would be greatly appreciated as it is becoming very frustrating for our teachers and student users. Thanks!
